would some 1/16 to 1/32 heat shrink tubing and a small piece of string with a knot tied in it work as well in a pinch when you don't have Lilian material? heat shrink tubing is insane cheap and light, and also works well with a small lighter.
Outstanding product update. I'm looking forward to ordering a Ayu II myself. Although the part where you purposely break the tip for demonstration makes me wince as if you were cutting off a finger.
